Popular Korean group Crayon Pop gets flak for its alleged costume knocks-offs. And now some are wondering if the group's newest single, "Lonely Christmas," doesn't rip off the theme song for anime Lupin III.

Here is "Lonely Christmas."

And here is the Lupin III theme from 1978.

One Korean YouTube user even made a direct comparison of each song's intro.

Maybe Crayon Pop paid to sample the theme? Maybe it doesn't sound like Lupin III? Maybe it's okay because this is just the beginning?
